Cold formed flitch beam
Cold formed flitch beam
(OP)
What are your thoughts on using cold formed steel back to back between lvls to make a flitch beam where a certain A36 steel thickness isn't available in a reasonable time limit. Design the steel to work and bolt through.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

With your plate elenent now flanged, will the LVL still add anything meaningful to the strength of the beam?

With lt. ga. stl. sections, how do you achieve bearing and load transfer under loads and at the end reactions, and btwn. the two different matr’ls? With that thin stl. matr’l. can you get good bearing/shear/load transfer with through bolts or other fasteners to really make the beam act as a composite member? If you can’t get a 1/4" stl. pl. the right length and width, why not use a 3/8" pl., or whatever, which is available. You might be better off putting the cold formed cee’s on the outside. That way you can fill the web holes with fasteners, with some better degree of certainty, for load transfer. Then provide bearing blocking at reactions, to make both matr’ls. bear.

Sure, if the numbers work. Is this really back to back CEE's and not a box section?
